DV, HDR10+ and a Firestick 4k
Posted: Wed Mar 31, 2021 7:06 pm
Is it the case that the Firestick 4k won't be able to play/properly decode an mkv file with both DV and HDR10+ metadata?

Yes

That's a bummer. Is there a way to strip out either the DV or HDR10+ meta after an x265 encode? Or does that have to be done prior to encoding?

Or maybe it's best to keep them both in the hopes that whatever prevents the Firestick from handling this properly will be fixed?

You can try this script to remove HDR10+: https://gist.github.com/quietvoid/175d7 ... 9eb1bd2c38
It only works on the raw hevc bitstream.
By default, x265 does not retain any metadata.

Yes, I've added HDR10+ json and DV RPU via command lines. Will this py script work even after the video is encoded? Thanks for your assistance.

Okay, and one more question. 
It seems the file I've created (muxed everything into a .ts file) does actually play on my Firestick 4k. I am playing it on a Samsung television so I presume I'm seeing the HDR10+, but I actually don't know how to verify that. I assume the issue is that if I were playing this on a television that supported Dolby Vision, I would not see DV triggered? FWIW, the file does properly show DV and HDR10+ in mediainfo.

Yes, it's just meant to skip HDR10+ info.
I only have a Dolby Vision capable TV, so I don't know how the Firestick behaves on HDR10+ Samsung displays.allomere wrote: ↑Thu Apr 01, 2021 12:57 amOkay, and one more question.
In the cases where it doesn't work, Dolby Vision is triggered but displays a black screen because there is also HDR10+ metadata, even if it can't be used by the TV.
Maybe it still works for HDR10+ only displays.
